To perform your query, I went to the contracts page of advanced search. I made sure that the date range was set to "All Years' and then I typed the word 'Trash' into the purpose field. After receiving my results, I exported and filtered my results, so that I was just looking at purpose column items that dealt with trash receptacles. Below is a list of the contract numbers that seemed to be most like your query. Please note that some of these contracts are for multiple items and are not amounts simply for trash receptacle. If you have any further questions, please feel free to contact me at nboone@comptroller.nyc.gov.
